<h3>Answer: B) he made his first mistake in step 5. He used the statement he was trying to prove as a reason.</h3>

The goal of the proof is to show that SP = SQ. This should be the very last line of the proof. We cannot use this as support or reasoning for other steps (because we haven't proven it to be true or not). This is known as circular reasoning. The term "equidistant" means "equally distant", so in other words, Jaime is trying to prove that S is equally distant to the points P and Q.

From earlier studies, it is believed that the percentage of students favoring a four-day school week during May and June of ever

Oksi-84 [34.3K]

Answer:

The minimum sample size 'n' = 862.538

Step-by-step explanation:

Step(i):-

Given the percentage of students favoring a four-day school week during May and June of every school year is approximately 85%

Given the Proportion of students favoring a four-day school week during May and June of every school year

p = 85% = 0.85

q = 1-p = 1-0.85 = 0.15

Given Margin of error = 2 % or 0.02

Level of significance = 0.90 or 0.10

The critical value Z₀.₁₀ = 1.645

Step(ii):-

The Margin of error is determined by

$M.E = Z_{0.10} \sqrt{\frac{p(1-p)}{n} }$

$0.02=1.645 X \sqrt{\frac{0.85(0.15)}{n} }$

Cross Multiplication, we get

$\sqrt{n} =1.645 X {\frac{\sqrt{0.125} )}{0.02} }$

√n = 29.369

squaring on both sides, we get

n = 862.538

Final answer:-

Sample size 'n' = 862.538
